quartz

Anyone have experience restoring quartz? Devitrification is a bitch. I never heat glowing red hot and I dab around 600-700. I buy cheap dhgate and no matter how well I qtip I can never get into the the imperfections in the quartz. I remove the banger and clean with 2 qtips soaked in 90% iso...

I'm using a quartz banger, does this look normal or is my rosin just not very good? Thanks
